Description

Water-based heat insulation material for outer wall and preparation method thereof
Technical Field
The invention belongs to the technical field of building exterior wall coatings, and particularly relates to an exterior wall water-based heat insulation material and a preparation method thereof.
Background
The external wall water-based heat insulation material is a functional water-based paint capable of blocking, reflecting and radiating sunlight near-infrared heat, and has good heat insulation, cooling, energy saving and consumption reduction effects on building roofs and walls.
As known, at present, in the areas of Guangdong, Guangxi, Fujian, Hainan and Jiangzhe Shanghai, etc., in China, rock wool boards (the heat conductivity coefficient is 0.041-0.045, the flame-retardant and moisture-absorption properties are large, but the heat-preservation effect is poor), integrated boards or other similar heat-insulating boards such as expanded polystyrene boards (the heat conductivity coefficient is 0.037-0.041, the heat-preservation effect is good, the cost is low, but the strength is poor) with the thickness of 3-3.5cm are still used, because the boards are generally fixed by dry hanging or using expansion bolts, and after the boards are fixed, the outside is hung with a net and is sprayed with corresponding functional coatings (also called as above). This type of insulation has at least the following disadvantages: firstly, the construction efficiency is low, the period is long, and the project progress is influenced; secondly, the weather resistance is poor, and the cracking situation does not occur for a long time, so that the appearance of the building is influenced, and the potential safety hazard caused by falling off is caused; thirdly, because the whole thickness is large, the overstaffed and the load of the outer wall are increased; fourthly, the labor cost consumed by construction is high.
Technical information related to building exterior wall coatings and capable of making up the deficiencies of the heat insulation structure to some extent can be found in published Chinese patent documents, such as CN101029206A (a nano-composite water-based heat insulation exterior wall coating and a preparation method thereof), CN106010029A (a water-based exterior wall heat insulation coating and a preparation method thereof), CN108570275A (a water-based radiation type exterior wall coating), CN108610823A (a water-based heat insulation exterior wall coating and a preparation method thereof), CN110157252A (a reflective heat insulation coating for an exterior wall) and CN102925022B (an energy-saving and environment-friendly water-based marble-imitated multicolor coating and a preparation method thereof), and the like. As is known in the art, it is common practice to prime the surface of building exterior walls prior to applying a coating thereto, and if the priming is not ideal, problems such as flaking, blistering and/or discoloration can occur after application of the coating. The reason is that most of the building exterior wall base materials are cement paste or concrete surfaces, and are characterized by more gaps and strong alkalinity, wherein the porous structure makes the water absorption of the building exterior wall base materials strong, the smooth effect of the surface of the base coat is influenced, the coating is easy to wrinkle, and the cracking of the finish coat and the waste of the finish coat are possibly caused by the rapid drying of the coating. In addition, the strong alkalinity can cause the chemical degradation of the coating resin, accelerate the aging of the coating and influence the service life of the coating. The primer material therefore plays a very important role in exterior wall coating systems, but there is no reference in the cited patent documents. As is also known in the art, the intermediate layer of the exterior wall coating system, which is supported by the aforementioned base coat layer, essentially acts as a thermal barrier, while the surface layer, which is supported by the intermediate layer, acts as a heat reflector, so that the choice of raw materials in the formulation of the intermediate layer and the surface layer, and the reasonable or non-rational amounts of the raw materials, are also important factors that cannot be regarded as being prejudicial, but there is also no reference in the above-mentioned patent documents.
In view of the above-mentioned prior art, the applicant has made useful research and repeated compensation, and the technical solutions described below have been made in this context.
